The operation isrepeated to :form additional pouches. In Fig'; 3:?ther pouch 4is shown with laterally=projectingend seals: 2 and 3. This pouchis representative of pillow-shaped rectansolar-pouches; in that it is rounded up at all four edges between the four corners- 4 illustrate the resulting pillow-shaped efiect.

When apouch of this general shape is shipped it is subjected to-various strains, as by'the start ing and stopping of a vehidleavhich is transporting it. This strain is so other weak portion of the pouch maybe ruptured by th'e temporary pressure of theliquid against it. The containerotthis invention relieves such strains b'y providing-a lateral support for-rounded portions of .sucha pouch jv; between. amour corners: 'I'hezseald ends of {the =ppuch are-gene eral-ly subjeeted to thegreatest strainand are the The .:liquid isz,filledsintorthe:tube above lamount: ofc'liquidc. has been introduced =is then'severed:

Figsp3 and great that a seal 'or portions of the pouch most apt to leak. Therefore, for a pouch sealed at each end, a support at each end without any side support reduces the tendency to leak. By supplying side supports as well as end supports the tendency to leak is further reduced, and four supports so placed reduce the strains on any pillow-shaped rectangular pouch, regardless of its construction, and reduce its tendency to leak.

Figs. and 6 show a container 6 of corrugated paper in which there are two compartments. It may be constructed with any desired number of compartments. At each end of each compartment there is a support 1. As shown in Fig. 8, the support 1 may be formed by folding a sheet of corrugated paper 8 four times. The inner two plies are united by adhesive 9 and the outside of the resulting support is united to the wall of the container 6 by adhesive 10. Any other type of support about /2 thick, for example a block of wood, is suitable.

The container shown in Fig. 6 contains several pouches H shown in dotted lines. Fig. 5 shows the container with the flaps opened ready for filling. The divider 12 may be a partition which is fastened to the container 6 or it may be entirely separate from the container and removable. The container 6 is deep enough to hold some 6 or 8 pouches in each of the two compartments. The pouches are laid flat, one on top of another, and the container should be level full so as to prevent any movement of the pouches after the flaps of the container have been closed. The closed flaps should provide a slight pressure on the top bag. The container is then turned and shipped on its side with the supports 1 on the bottom and top. Each pouch then rides in a vertical position supported laterally by dividers I2, and. the container sides, and with the four corners of the pouch unsupported and out of contact with the walls of the container. For purposes of economy the top supports 1 may be omitted if care is taken to be sure that the remaining supports 1 are on the bottom in shipping.

For fiat pouches measuring 8% inches long and 6 inches wide, filled with one quart of lubricating oil or other liquid, the distance between the end supports 1 should be 7 inches and the distance between the divider l2 and each side wall is 4% inches. The end supports 1 should be approximately 4 inches wide and /2 inch thick. A three-compartment carton or other container having two dividers, with inside measurements of 14 by 8% inches, and 13 inches deep is suitable for packaging twentyfour such pouches.

Fig. '7 shows an alternative design in which each pouch M is supported at the ends by corrugated board or other supports 15 and in which wider supports 16 are provided at each side of the package. The lateral support afforded by the dividers and sides of the container relieves the pouches of strains which are imposed upon them when shipped in a container without such supports, or with supports at only two ends. The end supports 15 are generally slightly thicker than the side supports 16.

Fig. 9 shows a carton blank 11 which is used to form the container l8 of Fig. 10. The blank is scored along the lines 19, 20, 2| and 22 to facilitate folding the blank along the edges of the panels 23, 24, 25,26 and,21,. The panels .23 and 21 overlap'iwhen the container is formed. The

blank is cut along the lines 28 which are ex?- 4 tensions of the sides of the flaps 29, 30, 31 and 32. The inner edge of each flap is scored along the line 33. The preferred container holds a single pouch 34, as illustrated in Fig. 10.

According to a preferred procedure for forming the container, the panels 23 and 21 are sealed together, and two of the flaps are fastened together, e. g., the flaps 3| and 32. The pouch is inserted and the other flaps 29 and 30 are united. As shown in Fig. 10 the ends of the pouch fit snug against the flaps which form the ends of the container. The end seals 35 are bent over, as shown, and the corners of the pouch extend beyond the supports provided by the respective fiaps. The pouch is held tightly, with slight pressure on its top and bottom sides, so that there is no lateral or vertical shifting of the pouch within the container. The support given by the flaps which are spaced inwardly from the corners relieves strains which would otherwise be set up within the pouch, and the tendency for leakage is greatly reduced.

Figs. 11 and 12 show, respectively, a blank 36 and a container 31 which is formed from it. The blank 36 is scored along the lines 33 and 39 to facilitate bending the end panels 40, 4|, 42 and 43. The blank is scored along the lines 44, 45, 43 and 41 to form the top and bottom panels 48 and 49, the side panels 53 and 5|, and the flap 52. The long, narrow flaps 53, 54, 55 and 5t alternate with flaps 40, 41, 42 and 43. The blank is scored along the lines 51, 58, 59 and 63 so that these four flaps may be bent inward. This leaves legs 35 (Fig. 12) between the long fiaps 53 to 56 and the edges of the side panels 50 and 5|.

The pouch is assembled by first uniting the narrow end flap 52 to the panel 48. Two of the wide end flaps, e. g., flaps 40 and 41 are treated with a slowly setting glue and curved in at one end and held in place by folding the narrow flaps 53 and 54 outside of them and uniting these narrow flaps by a fast-setting glue. The narrow flaps hold the wider flaps in place. The container illustrated in Fig. 12 is designed to hold four pouches, each of which may hold a quart of oil. These are stacked vertically in the container with one end of each on the curved flaps 40 and 41 and the corners at these ends of the pouches extending into the side corners of the container beyond the narrow flaps 53 and 54 which support the middle of the bag ends.

The four pouches fit snugly in this container.

The other end of the container is closed by curving the flaps 42 and 43 against one another, with a slowly setting adhesive between them, and then folding in the narrow, longer flaps 55 and 56 and uniting them by a fast-setting adhesive. The curved flaps at the ends of the container apply supporting pressure against the respective ends of the pouches, while permitting their corners to extend beyond the middle portions of the ends. If there are projecting flanges at the ends of the pouches these, of course, are bent over. The support of the curved ends relieves strains in the pouches and reduces the tendency of the seams to open and the pouches to leak.

Containers such as shown in Figs. 10 and 12 can be cheaply made and the support they give to the pouches which fit snugly inside of them will permit the pouches to b made of thinner gauge material than would otherwise be possible. Containers of the design illustrated in Figs. 10 and 12 may be constructed to hold one or more pouches.

These containers may be packaged in cartons, one to a carton, or several such containers may be packaged in a single carton.

Whether the pouches are packaged in containers such as shown in Figs. and 12 or in rectangular containers fitted with suitable supports, as shown in Figs. 5-7, the bags ar given end-seam support which protects them against strains in shipment, which would otherwise cause leakage.

Although described with reference to packaging of liquids, the invention is applicable to solids, especially powders such as dried milk, and small granules such as rice, raw popcorn, etc.
